    // 思路:
    // 1. 找对象 注册按钮, btn-login
    // 2. 给按钮注册点击事件
    // 3. 收集用户输入的内容, 用户名+密码 - 非空判断
    // 4. 发送请求 - 接口文档
    // 5. 针对请求, 做不同的处理
    // 5.1 请求成功 - 跳转到首页
    // 5.2 请求失败 - 轻提示
    let btnLogin = document.querySelector('#btn-login')
    let form = document.querySelector('form')
    btnLogin.addEventListener('click', async function () {

      const formData = serialize(form, { hash: true })
      // 针对用户名和密码的非空判断
      if (!formData.username || formData.username.trim() === '') return tip('请输入用户名~')
      if (!formData.password || formData.password.trim() === '') return tip('请输入密码~')
      if (formData.password.length < 6) return tip('密码长度不能小于6位~')
      // console.log(formData); // { username: 'zz', password: '123456' }
      // 使用 try catch进行错误的捕获
      try {
        const { data: { username, token } } = await axios.post('/login', formData)
        // 存储用户名 + token
        localStorage.setItem('username-103', username)
